The unmanned Mangalayaan space probe arrives, intact and functioning, in Mars orbit, making India the first country on Earth to successfully reach Mars on its first attempt. (A high failure rate among past Mars missions has plagued both the Russian and American space programs.) A 23-minute engine burn slows Mangalayaan down enough to be captured by Mars’ gravity, but leaves the vehicle with twice the fuel reserves expected for its projected six-month mission.
